Weight question

I’m really curious about this, I’ve been loosing weight somehow because my pants are starting to fall off and I’ve been told by family members my face is looking slimmer. However the scale still says I weigh 215 lbs. is it possible for me to loose some weight without it showing on the scale? I had my baby last June and struggled for a while loosing weight but like I said my pants are starting to fall down more and my face looking slimmer. Can anyone help me understand?
